Of the 36.4 million email addresses used, a little over 24
million were real email accounts. And that doesn't mean a lot
either. Ashley Madison doesn't verify email
accounts, which means anyone could plunk in any email
account, even if it wasn't their own. And, not everyone on Ashley
Madison was married. People were using the site to arrange
all kinds of hook ups.

All this to say take the chart below with a grain of
salt.It shows the number of valid email accounts at
10 large tech companies, according to Dadaviz.

IBM has over 350,000 employees and HP has nearly 300,000,
so statistically speaking it's not surprising that emails from
those two companies were most prevalent among big tech
companies on Ashley Madison. Cisco is a distant third.
